That part, at least, can be made simple: https://john-millikin.com/stateless-kubernetes-overlay-netwo...

None of that is part of Kubernetes, and you'll need it (or not) regardless of how you choose to handle process scheduling.

There's a sort of common idea that a "Kubernetes cluster" is an entire self-contained PaaS, and that (for example) monitoring in Kubernetes is somehow fundamentally different from what came before. It's easy to fall into the trap of creating an internal clone of Heroku, but Kubernetes itself doesn't require you to do so and it can be a lot faster to just run Nagios (etc).

Well, load balancing is part of Kubernetes (except that it does not provide a sane implementation), and tbh having to debug strange failures caused by seemingly-innocent Service configuration is my least-favorite part of Kubernetes.

I agree with you on other points.
